Graphics and Simulations (and Games), Oh My!
summary
A new Ruby gem called graphics gem (beta, install with --pre) provides a single-gem framework for visualizations, simulations and simple games with a grade‑school math API, double‑buffered update/draw/present loop, and over 20 primitives. Examples include a 28-line bouncing‑balls simulation where COUNT=1 → 25 changes behavior; Langston’s ants, boids, fluids, and a tank game using sprites and collision maps. The C layer uses SDL2 backend boosts FPS from ~30 to ~200, and the API can save PNGs, render text, and run headless update loops.
